Abstract

Two elastic and flexible arms are held at one end, and are enclosed by a locking ring sliding between the open and shut positions. There is a forceps clamping the clip at one end, while a lengthwise-sliding tube encloses the forceps in one end position, securing it in the end of the instrument. There is a face on one end of it acting against the locking ring so as to thrust this onto the arms of the clip. At its free end, the tube (16) forms an annular forceps (32) accommodating the locking ring. It is in turn enclosed by an outer tube (17) sliding on it between a position shutting the forceps and one releasing it. There can be protrusions at the open end of the forceps, engaging behind the locking ring in the shut position, and a stop can be provided on the inner tube, limiting movement of the outer one into the shut position.

Description

The invention relates to an applicator for applying and Loosen a surgical clip that rests two elastically arms bendable to each other, one end holding the arms cut and one around the arms, relative to the ar men in the longitudinal direction between an open position and egg ner closed position sliding locking ring includes, with a clip collet acting on the end section and egg nem longitudinally displaceable tube relative to the clip collet, that surrounds the clip collet in a clamping position and thereby fixing the end section in the clip collet and releases the clip collet in a release position and which has a stop surface for the locking ring, through which the locking ring when advancing the pipe relative to the clip collet on the arms of the clip from the Open position is moved to the closed position.

From DE 43 40 821 C1 it is known to mechanically specially operated ring for opening and closing Train collet to create seals. Also in DE 35 04 202 A1 a ring tensioning arrangement is over wrote. However, these devices are not for Application and detachment of a surgical clip determines where a clamping ring can be moved on the clip got to. The present invention is concerned with a Applicator for applying and releasing a surgical Clips where the clip is moved by moving a Locking ring is opened and tensioned.

Such an applicator is known from DE 43 19 829 C1 knows. With this applicator it is possible to create a clip grasp it in the open position at the desired application tion point and bring it there by pushing the Closing ring. In addition, with this Ap  plicator also detects a set and closed clip and by moving the locking ring in the opposite open direction. However it is necessary to lock the lock ring in a very specific way to train, he must namely outwards over the contour of the Lock ring protruding projections that for example by extending one of the clasps ring penetrating pin are formed. This before jumps are from a bayonet-like version of ver slidable pipe gripped so that then a withdrawal of the locking ring is possible. These ledges on Locking rings are undesirable, however, they can give rise to Injuries give and complicate the manufacture of the Clips and especially the locking ring.

It is an object of the invention, a generic Appli to train kator so that clips can also be created with it can be removed again, the locking rings none have specially adapted external structure.

This task is at the beginning of an applicator Written type solved according to the invention in that the Pipe at its free end as the locking ring taking ring collet is formed and that the tube is surrounded by an outer tube which is relative to the Pipe between a closing the ring collet and a releasing this position is displaceable.

The formation of the tube, which in itself can be opened and closed Closing the clip collet serves as a ring collet it is possible to open locking rings with any external contour increase and fix in the ring collet, namely  by advancing the outer tube. Withdrawing the Tube with the clamped locking ring enables in easy way to open the clip that is in the Clip collet remains clamped.

It is advantageous if the ring collet on its open NEN end carries protrusions when the ring is closed collet reach behind the locking ring. This will make the Locking ring in the ring collet not only by the Clamping forces held, but also by a form fit. On the one hand, it lies on the stop surface for the Lock ring on and on the other hand to the lock ring engaging projections of the ring collet so that with an axial displacement of the closed ring collet both taking the locking ring through ensure the clamping forces as well as the positive locking is steady.

It can be provided that the tube has a stop carries on which the outer tube when it is moved into the the ring collet strikes the closing position. Thereby is secured once when the ring collet is closed provides that the user reliably up to the outer tube advances a position closing the ring collet, on the other hand, if the pipe is pulled back, it becomes compulsory frequently carried the outer tube, the locking device ring collet is retained. Finally serves this stop and the outer tube on the tube un keep losing.

In a preferred embodiment, it is also provided see the clip collet over a rod with a  Handle is connected to the tube and the outer tube surround the rod concentrically and longitudinally on the handle are slidably mounted and that two actuators on the handle are stored by means of which independently of one another the pipe or the outer pipe in the longitudinal direction tion are movable. You get one in this way tubular shaft-shaped instrument that can be opened through narrow can be introduced into the body by can be operated from a location operated by the system position of the clip is removed. The can two displacement movements of the tube and the outer tube by the separate actuators independently of one another make others so that everyone can put on and take off necessary movements of the clip can be performed nen.

It is advantageous if the rod with the clip collet mounted on the handle so as to be rotatable about its longitudinal direction is. This makes it possible to use the clip in any To create the angular position.

In a preferred embodiment it is provided that move the tube into a guideway of the handle Lich inserted and only by the actuator is secured against being pulled out. This results in a particularly simple assembly. In particular, the Pipe associated actuator releasably ver with this be bound. This leads to the fact that after the Betä Tigungsgliedes the pipe in a simple manner from the Füh tion path of the handle can be pulled out, so that disassembly of the instrument is facilitated.  

It is also advantageous if the outer tube also move into a guideway of the handle is inserted and against pulling out only by the pipe is secured. This allows you to pull it out hen the tube from the handle at the same time Remove the outer tube, which is then to the rear of the tube can be subtracted, so you get a very simple one Disassembly and assembly of the instrument.

It turned out to be cheap if that Actuator associated with the outer tube together with the sem can be pulled out of the handle, if so is not permanently connected to the handle.

In a preferred embodiment, this is the pipe orderly actuator a pivotable on the handle ge stored handle lever that swivels to the tube.

The actuator associated with the outer tube is in front preferably a handle firmly connected to this.

For optimal adjustment of the handle to the hand size the user can still stand on the handle of the grip part, the position of which is relative to the actuators of the tube or Outer tube by moving the handle part relative to Handle is changeable.

The applicator 1 shown in the drawing comprises egg NEN handle 2 and a tubular shaft 3 mounted thereon, at its free end a receptacle for a clip 4 is seen before ( Fig. 1).

This clip 4 ( Fig. 4 to 10) comprises two elongated Ar me 5 , 6 , which are connected to each other at an end portion 7 and which in the open state enclose an angle with each other and can be placed against each other in the closed state by elastic bending against one another. Between the end portion 7 and a radially outwardly projecting collar 8 of the two arms 5 , 6 on the Ar men 5 , 6, a locking ring 9 is mounted longitudinally. When advancing the locking ring 9 from the end portion 7 to the collar 8 , the two arms 5 , 6 are elastically bent against each other and thus pivots ver in their closed position. An opening of the clip is done by moving the locking ring 9 in the opposite direction, the arms 5 , 6 open due to their elasticity as the.

The end portion 7 is circular cylindrical in the embodiment shown and extends only over a small length of the clip 4th

The handle 2 carries on its front side, that is on its clip receiving side facing, called a C-förmi, open to the rear bracket 10 and at its rear side, a bow-shaped, self-contained handle member 11 in a longitudinal guide 12 of the handle 2 längsverschieb Lich is stored and can be fixed in different positions along this longitudinal guide 12 by a clamping screw 13 . As a result, the distance between the bracket 10 and the handle part 11 of the hand size of the user is adjustable ( FIG. 1).

In the handle 2 there is a through bore 14 above the bracket 10 and the handle part 11 , into which the tubular shaft 3 is inserted. This tubular shaft 3 is composed of an elongated rod 15, a rod 15 that surrounds tube 16 and a tube 16 surrounding the outer tube 17th The rod 15 protrudes the farthest out of the tubular shaft 3 and is axially immovable, but freely rotatable, on the handle 2 there. By a spring-loaded brake 18 , the rod 15 can be secured against rotation, either by a step-by-step pattern or by a friction brake, so that a rotation of the rod 15 is only possible after a previous solution of the brake 18 or by overcoming a certain friction force . To twist the rod 15 , the water carries a rotary handle 19 at its rear end.

The tube 16 and the outer tube 17 are freely rotatable relative to the rod 15 and also relative to one another and are freely displaceable in the longitudinal direction. The outer tube 17 carries at its rear end a solid grip part 20 in the form of a recessed grip, this protrudes through a longitudinal slot 21 in the handle 2 and is arranged in this way on the outside of the handle 2 . The longitudinal slot 21 is open to the front end of the handle 2 .

On the handle 2 , a pivot lever 22 is rotatably mounted with a handle opening 23 , which engages with a fork-shaped end 24, a lateral projection 25 on the tube 16 . This projection 25 protrudes through a corresponding de longitudinal opening 26 of the outer tube 17 and, together with the end 24 of the pivot lever 22, forms a rotary drive, through which the tube 16 is displaced in the longitudinal direction when pivoting the pivot lever 22 .

The pivot lever 22 is releasably mounted on the handle 2 , this can be achieved, for example, by forming a bearing pin 27 of the pivot lever 22 as a push button. If this bearing pin 27 is displaced in the axial direction, it releases the pivot lever 22 , which can then be pulled down out of the handle 2 . This also moves the fork-shaped end 24 and releases the projection 25 , which means that it is then possible to pull the tube in the longitudinal direction forward from the hand 2 . The same applies with regard to the outer tube 17 arranged on the tube 16 , which is completely freely displaceable thereon and is also not fixed in the longitudinal direction in the handle 2 . The tube 16 and the outer tube 17 are thus secured solely by the pivot lever 22 in the longitudinal direction in the handle 2 , the rod 15, however, is held in the handle 2 in the longitudinal direction immovable Lich.

The rod 15 carries at its free end a clip collet 28 open towards the front side. This is formed by a cylindrical sleeve 29 with longitudinal slots 30 through which the sleeve 29 is divided into individual jaws 31 . The jaws 31 can elastically spring inwards and outwards in the radial direction ( FIG. 4).

The clip collet 28 is dimensioned such that the cylindrical end portion 7 egg nes clip 4 can be inserted from the open end face and rests with its peripheral surface on the inner surface of the jaws 31 . As long as the jaws 31 of the clip collet 28 are not compressed radially, the end section 7 can be pushed in the longitudinal direction without further ado in the clip collet 28 .

A radial clamping of the jaws 31 can be achieved through the tube 16 . This can namely be advanced in the longitudinal direction via the clip collet 28 and then presses the jaws 31 resiliently inwards. As a result, he gives himself a frictional or, if appropriate, the form of the inner wall of the clip collet 28 , the end section 7 also being positively fixed in the clip collet 28 . The clip 4 is thereby fixed in the clip collet 28 and can now be brought to any desired location with the applicator 1 ( FIG. 5).

The tube 16 is formed in the region of its free end as a collet 32 . For this purpose, several longitudinal slots 33 are made in the tube 16 from the free end, which divide the free end of the tube 16 into jaws 34 . These jaws 34 are similar to the jaws 31 to be pressed resiliently, namely through the outer tube 17 , which can be pushed in an advanced position over the free end of the tube 16 and thereby clamps the jaws 34 radially inwards. The feed movement of the outer tube 17 on the tube 16 is limited by a collar-shaped stop 35 on the edge of the tube 16 .

The inner diameter of the tube 16 is selected so that the inner wall of the tube 16 closes the clip collet 28 when these two parts abut one another. Immediately adjacent to the free end of the tube 16, however, the interior of the tube 16 expands in stages and forms a receiving space 36 for the locking ring 9 there . The stage 37 in the transition from the interior of the tube 16 to the receiving space 36 forms a stop surface for the locking ring, which is completely accommodated in the receiving space 36 when struck at this stage 37 . If the jaws 34 of the ring collet 32 are not overlaid by the outer tube 17, the locking ring 9 can be easily inserted into the receiving space 36 in the longitudinal direction or out of it again.

However, if the outer tube 17 provided to the stop 35 is advanced and the jaws 34 inwardly biased, is the locking ring is clamped in the collet ring 32. 9 This can be done solely by the clamping forces between the inner wall of the receiving space 36 and the outer wall of the locking ring 9 , in the illustrated embodiment, however, this is supported by an annular projection 38 projecting into the receiving space 36 at the end edge of the tube 16 . This projection 38 jumps very little into the receiving space 36 , so that when the jaws 34 are open, the locking ring 9 can easily be inserted past the sem projection 38 into the receiving space 36 or pulled out of it. In the case of inwardly clamped jaws 34, however, this projection 38 engages behind the locking ring 9 and thereby holds it positively in the receiving space 36 .

The procedure for creating a clip 4 is as follows:
With the tube 16 withdrawn and the outer tube 17 withdrawn, a clip 4 is inserted with its end section 7 into the clip collet 28 , the locking ring 9 is withdrawn in the direction of the end section 7 , so the clip 4 is open ( FIG. 4).

By pushing the tube 16 by means of the pivot lever 22 , the clip collet 28 is first closed, so that the clip 4 is fixed in it. When further pushing the tube 16 , the locking ring 9 is inserted into the receiving space 36 and lies on the stage 37 . If the tube 16 is now pushed further forward, it simultaneously pushes the locking ring 9 on the clip 4 in the direction of the federal government 8 , so that the arms 5 and 6 of the clip 4 are bent against each other. The end section 7 remains clamped in the clip collet 28 , so that the locking ring 9 can also be advanced if frictional forces have to be overcome.

As soon as the locking ring 9 has reached its closed position, the tube 16 is released again by pivoting the pivoting lever 22 in the opposite direction, finally, even when the tube 16 is completely retracted, the clip collet 28 . The applicator 1 can then be easily removed from the set and closed clip 4 who the.

When applying the clip it is important that the plane of the clip can be rotated by turning the rod 15 and thus by turning the clip collet 28 , so that the contact position can be adapted to the anatomical conditions.

If an applied and closed clip to be released, one places the applicator 1 with retracted tube 16 and retracted outer tube 17 with its clip collet 28 on the end portion 7, so that the Endab cut is arranged in the clip chuck 28. 7 In the water position, the clip 4 is fixed in the clip collet 28 by advancing the tube 16 . The tube 16 is advanced until the locking ring 9 dips into the receiving space 36 . By pushing the outer tube 17 , the ring collet 32 can be closed, the projection 38 engaging around the locking ring 9 .

In this position, the locking ring 9 can be retracted from its closed position into the open position by withdrawing the tube 16 with the aid of the pivot lever 22 . When the tube 16 is retracted, the outer tube 17 is inevitably retracted because it strikes the stop 35 , which acts as a driver.

After the displacement of the locking ring 9 in the open position, the clip 4 opens and can now - firmly clamped in the ring collet 32 - be removed from the jetty by means of the applicator 1 .

By completely withdrawing the tube 16 and thus the outer tube 17 , the ring collet 32 is opened so that the clip 4 can then be removed from the applicator 1 .
